I did a color correct pass and increased the contrast with curves, did a small sharpen pass and then an extra sharp (lab/lightness 500/.5/0) on just the rings. Once I desaturated the background petals I ran a slight diffuse glow on it and I think I probably finished it with scott kelby's '3 step portrait finish' (which you can find on the web in a bunches of places )
